    Have tried it for a blast pot gun BUT you do need to get the right (older type ?) plug as most (well the daughters fiesta ones) have a hard section in the center electrode about half way through. Think older plugs would almost come a part once separated from the metal threaded part.

    How long does it take to modify a spark plug?
     
  7. I used to do it, takes about a minute to drill down the centre electrode. I would do a few at a time.

    I could also use a small hose (like 5 cm) after the ball valve and use the jubilee clip there, right?

    Until I buy the the tungsten nozzle I am going to try the car spark plugs, but my "sandblast gun" is a 1/2" ball valve which has more than 10mm hole and the small hole of the spark plug is 3mm how do I evenly reduce the size (is there like any rubber piece?), I tried it without anything and the gun gets jammed with abrasive
